Dynamic Simulation Issue

steamyrendini69 — Thu, 20 Oct 2022 17:18:30 GMT

Hi friends,

I am trying to use Dynamic Simulation to help calculate the force a linear lift needs to exert to lift a scissor mechanism structure. However, when I run the simulation, it seems that my tangent constraints specifically are ignored. Has anyone encountered this issue before? Referencing the attached screenshot:

At 'A', there is a wheel that is supposed to sit tangent to the above surface

'B' there is a wheel that is supposed to sit tangent on top of this surface.

'C' this is the lifting leg I am trying to find the required force for.

Thanks so much for any help or recommendations!

Cheers,

Jake

Attach your assembly here.

Have you defined your 2D Contact Joint(s)?

Have you defined Gravity?
